JJazzLab Dark JJazzLab Dark JJazzLab Spain Demo    

New features 4.1.0

  • FluidSynth, the JJazzLab builtin synth
    JJazzLab 4 now embeds a ready-to-use builtin synth based on FluidSynth.

  • New JJazzLab Toolkit for developers
    All JJazzLab core in one java library: it’s easy to experiment!

  • Improved notes editor
    New Humanize feature, new playback loop zone, new velocity window.

  • Import/export text-based leadsheets, e.g. |3/4 A7b9 | Dm7 Db7 | C7M | % |
    For example copy measures from JJazzLab and paste in a text editor. Works both ways. You can also drag a text file into a song.

  • And many more…
    Bug fixes, light theme improvements, improved .sng file format, etc.

Consult the online doc if you need detailed INSTALLATION INSTRUCTIONS.

Windows

JJazzLab-4.1.0a-win64-setup.exe     md5sum: 7b22dfef0c319daca8c1202f12592f24

If you get a Windows Smart Screen alert, click on More info, this will let you run the installer anyway. JJazzLab is NOT a malware! You can use md5sum to check file integrity.

When installation package is new, Windows security servers don’t have enough statistics to evaluate its “security reputation”. Alert will disappear soon, once enough people have run the software.

Mac

You must first install FluidSynth yourself (I recommend via Homebrew).

Then:

Linux Ubuntu/Debian family (x64)

Download the .deb file and install it as shown below.

jjazzlab_4.1.0-1_amd64.deb      md5sum: d65b6f57f1cc00b901606197293f3e37

sudo apt-get install ./jjazzlab_4.1.0-1_amd64.deb    # this will also download and install fluidsynth (>=2.2.0) if required

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.

Linux OpenSUSE family (x64)

Download the .rpm file and install it as shown below.

jjazzlab-4.1.0-0.x86_64.rpm     md5sum: c8f5e581c8e5f89ad88b26577d4ccf6a

sudo zypper install ./jjazzlab-4.1.0-0.x86_64.rpm      # this will also download and install fluidsynth (>=2.2.0) if required

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.

Linux others (x64)

You must first install FluidSynth (>=2.2.0) yourself.

Then:

JJazzLab-4.1.0-linux-x64.tar.xz      md5sum: 01cce8ccb5e532b77a81c62dfda2c2e7
Extract then run file bin/jjazzlab to start JJazzLab.

If FluidSynth makes some “crackling” noise, make sure your Linux is optimized for audio applications.

Consult the INSTALLATION INSTRUCTIONS ON LINUX if required -distribution on the many Linux distros is not always easy…
